He did indeed complain that the laptop keyboard was too small for his fat fingers and asked if he could buy a full sized keyboard, connect it to his laptop and would it work. We all shouted YES! and after much faffing he said that he had purchased a new keyboard from Tesco or somesuch. There was no discernable improvement in his typing ability.
If it is the new keyboard playing up then he only has to disconnect it to solve the problem but as ever with our Nick nothing is as simple as it seems.
